Why might rocks in a creek hurt your feet more than the same rocks in deeper water?

The rocks in the deeper water don't hurt as bad because you are not putting all your weight on them... You know how someone can carry you on their back in the water but not out of it... that is because the water holds you up a bit... So you see! The waterdoesn't allow all your weight to fall onto the rock! This is why rocks in a creek might hurt your feet worse then the rocks in deeper water!
